After completing this chapter, you will be able to:
Derive differential equations for mass transfer in Cartesian coordinates in flux form.
Express these relationships in vector form so that they can be used for any coordinate system.
Define the mixture velocity and the diffusion flux.
Examine some properties of the diffusion flux.
State some forms of Fick’s law for binary systems depending on the frame of reference used.
Derive the differential equation for the concentration field by combining the equation in the flux form with Fick’s law.
State the boundary conditions for many standard cases.
Show how averaging of differential models leads to mesoscopic and macroscopic models, and describe ...
